Developing Future Biologists (DFB), is a graduate student- and postdoc-led organization dedicated to ensuring that the next generation of biologists, regardless of race, gender, or socioeconomic status, have the opportunity to learn core developmental biology concepts and are made aware of the opportunities that exist to pursue a career in science. To achieve this mission, DFB (1) designs and implements an immersive weeklong short course to provide undergraduates with hands-on lab experience and career development activities, and (2) fosters long-term mentoring and networking opportunities to DFB participants. At the same time, DFB provides its trainee instructors with invaluable experience in course design, teaching, mentoring, and more.
